Safety & First Aid (Smart Flame & Smoke Alarm System)

Source:

Construct a cardboard mini home equipped with an IR flame sensor and gas sensor. Bringing an IR light source (simulated fire) near the home triggers flashing red lights, a loud alarm, and evacuation voice instructions.

Categorisation

Props & Materials Required

  • •Mini cardboard house model
  • •IR flame sensor module (detects 760nm-1100nm IR light)
  • •MQ-2 gas/smoke sensor module
  • •Loud alarm buzzer + Red strobe LED
  • •ESP32 controller board
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Inspect Home Safety Sensors

Locate the IR flame sensor on the roof and smoke sensor inside the kitchen model.

2

Simulate Fire Hazard

Shine a safe IR flashlight / TV remote signal toward the flame sensor.

3

Sensor detects IR flame light! Red LED flashes strobe pattern, alarm sounds, and speaker shouts: 'FIRE DETECTED! EVACUATE IMMEDIATELY! CALL 101!'

4

First Aid Kit Challenge

Open the mini first-aid box. Scan NFC cards for Band-Aid, Antiseptic, Burn Ointment to match safety scenarios!

Why It Works & Notes

Safety rules are vital life skills. Experiencing how smart sensors detect invisible infrared flame light and gas before humans can see smoke makes home safety technology understandable and empowering.
